The aerosol num.er concentration and size distribution as well as size-resolved particle chemical com.osition were m.asured during haze and photochemical sm.g episodes in Shanghai in 2009. The num.er of haze day. accounted for 43%, of which 30% was severe （visibility.〈 2 km. and m.derate （2 km.〈 visibility.〈 3 km. haze, m.inly.distributed in winter and spring. The m.an particle num.er concentration was about 17,000/cm. in haze, m.re than 2 tim.s that in clean day.. The greatest increase of particle num.er concentration was in 0.5-1μm.and 1-10 μm.size fractions during haze events, about 17.78 tim.s and 8.78 tim.s those of clean day.. The largest increase of particle num.er concentration was within 50-100 nm.and 100-200 nm.fractions during photochemical sm.g episodes, about 5.89 tim.s and 4.29 tim.s those of clean day.. The particle volum. concentration and surface concentration in haze, photochemical sm.g and clean day. were 102, 49, 15 μm./cm. and 949, 649, 206 μm./cm., respectively. As haze events got m.re severe, the num.er concentration of particles sm.ller than 50 nm.decreased, but the particles of 50-200 nm.and 0.5-1μm.increased. The diurnal variation of particle num.er concentration showed a bim.dal pattern in haze day.. All soluble ions were increased during haze events, of which NH4, SO24- and NO3 increased great/y. followed by.Na＋, IC, Ca2＋ and CI-. These ions were very.different in size-resolved particles during haze and photochemical sm.g episodes.
